The heavy winter storm dumped more than 20 inches of snow on Columbus on Saturday, while blizzard conditions shut down highways and stranded air travelers in the region.
The storm then swept into the East Coast, battering Pennsylvania and New Jersey with a line of thunderstorms. By early Sunday, tens of thousands were left without electricity.
High winds in Ohio whipped the snow into 3-foot-tall drifts in some places and cut visibility to less than a quarter mile, the National Weather Service said.
"We will get through this," Gov. Ted Strickland said Saturday. "The snow will stop, the wind will cease, and the sun will shine. But until that happens we need to be smart, take care of ourselves and attempt to be helpful to others."
The storm, which rolled in Friday, dumped 20.4 inches of snow on Columbus, breaking the city's previous record of 15.3 inches set in February 1910, the weather service said. Cincinnati and Cleveland received about a foot of snow.
State officials urged motorists to avoid the roads. At least nine counties closed roads to non-emergency traffic, meaning that anyone caught driving was subject to arrest unless they were involved in an emergency.
In Indiana, 14 inches of snow fell in Milan, which is about 60 miles southeast of Indianapolis, said the weather service said.
Roads were impassable, prompting the county to declare a local emergency banning all vehicles except for emergency vehicles from the roads, authorities said.
"The winds are starting to pick up now, so we expect some of them to be pretty treacherous," Ripley County sheriff's Deputy Brian Maynard said of the roads.
It was a continuation of the storm that on Friday piled up snow a foot deep in Arkansas and blacked out thousands of homes and businesses from that state to the Great Lakes. Louisville, Ky., and parts of Tennessee got up to a foot, while northern Mississippi got 5 to 7 inches of snow, the weather service said.
Secondary roads and bridges were snow-covered and icy in Tennessee and Kentucky on Saturday morning, but much of that had melted by the afternoon when temperatures climbed into the upper 30s.
One Ohio traffic death was blamed on the weather Friday, with two in New York state and one in Tennessee. Two people were killed as tornadoes struck several Florida communities.
Three men in the Cleveland area and one in the Columbus area died Saturday while shoveling snow, authorities said.
At Port Columbus International Airport, a plane skidded a few hundred feet off a runway while landing late Friday, but no one was hurt, airport spokeswoman Angie Neal said.
A warm-up was not expected until Tuesday, when the forecast called for temperatures in the lower 40s, the weather service said.
Flooding could be a concern if it warms up too quickly, said Nancy Dragoni, director of the Ohio Emergency Management Agency.
"We're hopeful that there'll be enough time for some of the water to go down in the rivers and creeks and streams so we can absorb the snow when it melts," she said.
New Jersey got as much as 3 inches of rain from the storm, and heavy wind and rain caused power outages and downed trees late Saturday there, as well as in Pennsylvania and New York. More than 100,000 customers were without power during the peak of the storm in New Jersey, utility companies reported.
In the Philadelphia area, Peco Energy officials say up to 80,000 customers are without power due to rain and high winds.
